The total mass of your catch is 13.1 kg
Since you have three fishes a bass, a rock cod, and a salmon with masses of 1.07 kg, 6.0 kg, and 6.05 kg, respectively,
The total mass of your catch = mass of bass + mass of rock cod + mass of salmon
= 1.07 kg + 6.0 kg + 6.05 kg
= 13.12 kg
Since the total mass of your catch is 13.12 kg and we have three catches with two catches to two decimal places and one catch to one decimal place.
We cannot have more decimal places in our answer than the number of decimal places in the number with the least number of decimal places.
Since the least number of decimal places is in the mass of the rock cod which is 6.0 kg, the total mass of our catch is thus 13.1 kg to one decimal place.
So, the total mass of your catch is 13.1 kg

An experiment is conducted to determine how the arm length of a pendulum affects its period. The experimental design calls for varying the length of the arm and the mass of the bob.
Which is true about this experiment, based on good experimental design?
Only the arm length should be changed. The mass should remain the same.
Only the mass should be changed. The arm length should remain the same.
The force applied to the mass should be varied for each trial.
The material the arm is made of should be varied for each trial.
Answer:
Option (I)
Explanation:
The independent varible is arm length. Therefore, to eliminate the effect of other factors and make a valid and effective conclusion, only the arm length should be changed, while other factors (mass, force and materials) should remains the same.
Answer: Only the arm length should be changed. The mass should remain the same.

Fluorine has 7 valence electrons. Which charge is its ion likely to have?(1 point)
1+
5+
1–
5-
Answer:
1–
Explanation:
The fluorine is the element with biggest electronegativity in the periodic table, so it usually always take an electron and gets charge 1–
The valence electrons that Fluorine possesses is 7. Then, the charge of its ion would most probably be:
C). 1–
Fluorine is the element having F as its symbol and 9 as its atomic number(9 protons).
As we know, valence electrons are the electrons that are available in the surface shell of the atom. This is the reason that such electrons can make bonding with some other atoms as well. Since Fluorine contains 7 valence electrons, it would have a charge of 1– because it will acquire extra electrons to form the bond. Fluorine's valence shell would contain [tex]2s^{2} 2P^{5}[/tex] i.e. 7 valence electrons.Thus, Fluorine is the chemical element that possesses the highest electronegativity i.e. of around 3.98.Learn more about 'chemical elements' here:

A train is moving with the velocity of 10m/s . It attains an acceleration of 4m/s after 5 sec . find the distance covered by train at that time.
pls guys i have a serious question thats in my brain for a long time.
Find the highest acceleration
best answer = brainlist
The greatest acceleration on the graph is 4 m/s² .
"Acceleration" means how fast velocity is changing.
Changing velocity means changing speed OR direction.
This graph doesn't tell us anything about the direction of motion, so we can only work with speed.
The "greatest" acceleration means the biggest change of speed in the shortest time.
Your picture of the graph is pretty fuzzy, and I'm not sure I can actually read everything correctly.
The y-axis looks like it's velocity, and I THINK the numbers are 0, 20, 40, and 60, in meters per second.
The x-axis looks like time, and I THINK it's marked 0, 10, 20, 30, 40, 50, 60, 70, and 80, in seconds.
Now, each straight piece on the graph shows a change of velocity and a change of time. So the SLOPE of each piece is the acceleration of that piece.
==> On the first piece, from 0 to A, the velocity changes from 0 to 20 m/s, and the time changes from 0 to 20 sec. The slope of that piece is (20 m/s) / (20 sec), so the acceleration is 1 m/s² .
==> On the level piece from A to B, the velocity is 20 m/s. It doesn't change, from 20 to 30 sec. It has no slope, so the acceleration is zero.
==> On the piece from B to C, the velocity rises (60 - 20) = 40 m/s, and the time changes (40 - 30) = 10 sec. The slope is (40 m/s) / (10 sec), so the cceleration on that piece is 4 m/s² .
==> Finally, on the last piece, from C to D, the velocity DROPS from 60 to 0 m/s, during the time from 40 to 80 sec. The change in velocity is -60 m/s, and the change in time is 40 sec. So the slope of the piece, and the acceleration, is (-60 m/s) / (40 sec) = -1.5 m/s² .
The greatest acceleration shown on the graph happens along the line segment from B to C, from 30 to 40 seconds. During that time, the velocity changes from 20 to 60 m/s. That's an acceleration of 4 m/s² .

The spirit rover could move across the Martian landscape at a maximum of 2.68 m/mi. How many minutes would it take for it to travel 10.4 m, the length of a typical classroom?
Answer:
Explanation:
Thks for answer
The spirit rover could move across the Martian landscape at a maximum of 2.68 m/mi. It would take 3.88 minutes to travel 10.4 m, the length of a typical classroom
What is speed?The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is meter/second. The generally considered unit for speed is a meter per second.
In this scenario, a body would move at a speed of 4 meters per second while covering a distance of 2000 meters in 50 seconds.
As given in the problem The spirit rover could move across the Martian landscape at a maximum of 2.68 m/mi.
The speed of the spirit rover = 2.68 m/mi
as we know
speed = distance /time
2.68 m/mi = 10.4 meters/ time in minutes
time in minutes = 10.4/2.68 minutes
= 3.88 minutes
Thus. it would take 3.88 minutes for the spirit rover to travel 10.4 m, the length of a typical classroom
